Cation-Exchange IC Columns

A complete family of columns for inorganic cations and amines

You'll get high-resolution separation of inorganic cations, ammonium, and amines using these Thermo Scientific™ Dionex™ IonPac™ cation-exchange columns. They are excellent for separations of alkali metals, alkaline earth metals, alkylamines, alkanolamines and biogenic amines.

Dionex™ IonPac™ CS20 IC columns High-capacity column for common cation and amine analysis. Complementary column to the Dionex IonPac CS18 and Dionex IonPac CS19 that elutes amines away from interfering matrix ions. Requires high-pressure IC. Group I and Group II cations, and amines including methylamines, ethylamines, ethanolamines, and alkanolamines in diverse sample matrices. Tolerates acidic samples.
Dionex™ IonPac™ CS19-4µm IC Columns High-resolution separation of cations, small polar amines, moderately hydrophobic amines and polyvalent amines. Requires high-pressure IC for faster runs. This newer column replaces the Dionex IonPac CS18 column. Common cations and amines in environmental and power plant waters, chemical process and refinery scrubber solutions, personal care products, and food and beverage samples.
Dionex™ IonPac™ CS19 IC Columns For common cations, small polar amines, moderately hydrophobic amines, and polyvalent amines. Operates under 3000 psi on standard IC systems. This newer column replaces the Dionex IonPac CS18 column. Common cations and amines in environmental and power plant waters, chemical process and refinery scrubber solutions, personal care products, and food and beverage samples.
Dionex™ IonPac™ CS18 IC Columns Low-capacity column for gradient separation of polyvalent and moderately hydrophobic amines in complex matrices using aqueous eluents and elevated temperature. Polar amines (alkanolamines and methylamines) and moderately hydrophobic amines (biogenic amines, diamines and polyamines) in diverse sample matrices, including foods and beverages.
Dionex™ IonPac™ CS17 IC Columns Gradient separation of polyvalent and more hydrophobic amines, biogenic amines, and diamines. This newer column replaces the Dionex IonPac CS14 column. Hydrophobic amines in complex matrices without solvent, such as environmental and power plant waters, chemical process and refinery scrubber solutions, personal care products, and food and beverage samples.
Dionex™ IonPac™ CS16-4µm and CS16-Fast-4µm IC Columns Highest-capacity, high-resolution cation columns to analyze disparate concentration ratios of closely eluting cations such as sodium and ammonium in complex matrices. Requires high-pressure IC for faster runs using higher flow rates. Short-chain amines and trace-level ammonium with high sodium concentration (and vice-versa) in complex industrial samples. Best cation column for low pH samples.
Dionex™ IonPac™ CS16 IC Columns Highest-capacity cation column to separate high- to low-concentration ratios of sodium and ammonium in complex sample matrices. This newer column replaces the Dionex IonPac CS15 column.
Short-chain amines and trace-level ammonium with high sodium concentration (and vice-versa) in complex industrial samples.
Dionex™ IonPac™ CS15 IC Columns Moderate-capacity column with unique selectivity for samples with high ammonium to low ethanolamine ratios. The Dionex IonPac CS16 is a newer, ideal alternative to this column. Ethanolamines and ammonium cations present in disparate concentration ratios in diverse sample matrices. Ethanolamines elute before ammonium.
Dionex™ IonPac™ CS14 IC Columns Moderately low-capacity cation-exchange column for analysis of aliphatic amines, aromatic amines, and polyamines using MSA or sulfuric acid eluents. The newer Dionex IonPac CS17, CS19 and CS19-4µm columns are newer alternatives to this column. Aliphatic amines and Group I and Group II cations in diverse sample matrices.
Dionex™ IonPac™ CS12A IC Columns Separation of mono- and divalent cations including manganese. Use Dionex IonPac CS16 column for high- to low-concentration ratios of adjacent eluting cations. Common cations and ammonium in drinking water, process waters and industrial samples. Trace cations in various matrices.
Dionex™ IonPac™ CS12 IC Columns High-capacity column for fast isocratic separation of common inorganic cations in diverse matrices. The Dionex IonPac CS12A column is a newer alternative to this column. Fast, isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium using methanesulfonic or sulfuric acid eluents in diverse sample matrices.
Dionex™ IonPac™ CS11 IC Columns Low-capacity, cation-exchange column for isocratic separation of inorganic cations using HCl with DAP eluents. The Dionex IonPac CS12A column is a newer alternative to this column. Common inorganic cations and aliphatic and aromatic amines in diverse industrial sample matrices.
Dionex™ IonPac™ CS10 IC Columns Low-capacity, cation-exchange column for isocratic separation of inorganic cations using HCl with DAP eluents. The Dionex IonPac CS12A is a newer alternative to this column.   Common inorganic cations and aliphatic and aromatic amines in diverse industrial sample matrices.
Dionex™ IonPac™ SCS 1 Silica Cation Separator Columns For nonsuppressed conductivity detection or single-column IC (SCIC). Recommended when extended calibration linearity for ammonium or alkanolamines is required.  Common inorganic cations, ammonium, select alkanolamines, and transition metals such as zinc and copper.
